Bonded PV Arrays Could Provide Safer Solar Power

Most electricians are referred to as “indoor wiremen” and are experts at installing electrical equipment indoors, but some lack experience working with exposed cables and outdoor equipment bonding. Traditional methods of bonding and grounding include the extensive use of bare copper conductors for equipment bonding. While copper is preferred for bonding steel, it is not the best choice around exposed aluminum members. Aluminum and copper should not come into direct contact due to galvanic corrosion issues. Over time, copper has a tendency to erode aluminum and can even cause structural failure of thin aluminum extrusions when in direct contact.
